If you want to save thousands of dollars and avoid costly legal battles, ask your custom homebuilder the following questions before you sign a contract or put any money down for your home.

Down Payment and Pricing Questions

Two Golden Rules

Finally, there are two golden rules to follow when dealing with homebuilders. First, never sign anything with your homebuilder until you have read the fine print. If there is something that you do not understand, seek advice from an independent homebuilder, or consultant, or obtain legal advice. Remember that there is no ‘cooling-off’ period. So, once you sign a home building contract, you cannot withdraw from it if you change your mind.

Second, ensure you keep a written copy of everything important and that all requests, confirmations, and changes are in written correspondence; email is the best way to do this.
